Windows 10 builds 15063.675, 14393.1797 now available - here's what's new

We're less than two weeks away from the next Patch Tuesday, but Microsoft today released a few cumulative updates for multiple versions of Windows 10. The build numbers are minor increases from the ones released earlier this month, and they only include a couple fixes total.

The updates are for users running versions 1703, 1607, and 1511, so there's nothing for those that installed the Fall Creators Update (version 1709) earlier this month.

For those on the Creators Update, you'll see KB4049370, or build 15063.675, which you can manually download here. It contains the following fix for Surface Laptops:

  • Addressed issue where after installing KB4038788, some Microsoft Surface Laptops boot to a black screen. Additionally, you must press the power button for a long time to recover.

The update also contains a range of known issues:
